Identifying fleas

The world is host to over 2,000 species of flea, and they’re a problem almost everywhere. Most common is Ctenocephalides felis, the "cat flea". Despite its name, the cat flea affects both dogs and cats, and wildlife such as possums - and can be unpleasant for pet owners, too. Most dogs will pick up fleas often throughout their lifetime. Even pets that never go outdoors are at risk from fleas that can find their way into their home.

Flea Eggs


Female fleas lay eggs while on your dog and can produce 40 to 50 eggs a day, leaving them to fall off your dog and all over your home. Each egg can hatch into larvae in as little as 1 to 10 days, and as many as 30% will develop into adults.

Flea Larvae


Flea larvae live in carpets, fabrics, and small crevices in your dog’s environment. They feed on adult flea faeces and organic material they find until they’re ready to develop into pupae.

Tick Nymph


Pupae develop into adult fleas inside tiny cocoons. Here they can stay dormant for long periods and come out in response to heat, carbon dioxide and movement.

Adult Flea

Adult Flea

Once on your pet, adult fleas spend the rest of their lives there, feeding and laying eggs that infest your home within a matter of days.

How to check for fleas

  • Step 1.

    Regularly checking for fleas should be part of routine pet care.

  • Step 2.

    Try parting the coat near the base of the tail using your hands or a flea comb and look for movement. Most fleas grow to about the size of a pinhead and will move or jump when disturbed.

  • Step 3.

    Even if you don’t see any fleas, have a look for dark, pepper-like particles on the surface of your pet’s skin and coat. These may be ‘flea dirt’, which are flea droppings.

  • Step 4.

    You can easily confirm this by dabbing some of this material with a wet paper towel or cotton ball. If you see dark reddish brown or orange swirls, this is flea dirt and confirms that the pet has fleas. If you suspect fleas are present, talk to your vet about treatment with Bravecto.
